Question

How much power does it take to lift 30.0 kg 10.0 m high in 5.00 s?

Answer 1

Answer:The defining equation for power is work done divided by time taken. This is equivalent to the energy used divided by time taken according to the work energy theorem. Let's assume conservative forces with no friction. The work done is the forest times displacement which is mgh and there you have your potential energy formula divide that by time and you're all set.
